This movie is similar to...

The video/computer game "Manhunt". Don't you agree? Sure, it takes place in a jungle (maybe "Manhunt" mixed with "Far Cry"), but the "survive the predators" concept applies here (except for the fact that the island has multiple victims). Also, Bas Rutten looks A LOT like James Earl Cash (the protagonist in "Manhunt"). If there is ever a movie adaption of "Manhunt", Bas Rutten should star in it!
